Abstract To analyze the damage mechanism of rural buildings in the Ms 6.8 Luding earthquake, typical seismic damage characteristics of masonry-timber structure, brick-concrete structure and RC frame structures were summarized, based on the damage investigation of rural buildings in Moxi town, Detuo town, Yanzigou town. The classifications, statistics and analyses of seismic damage levels were carried out for rural buildings in the area with the intensity is assessed at Ⅸ degrees. The results from the investigation and analyses show that masonry-timber structure and brick-concrete structure were the most obvious structural forms of earthquake damage and obvious in this earthquake, the seismic damage of frame structure is light, generally, and the number of basically undamaged frame structures accounted for 72.5%. The typical seismic damages of the masonry-timber structure and brick-concrete structure appear to be uneven settlement of a foundation, wall cracking, floor (roof) damage, non-structural component damage, and overall collapse. The seismic damages of RC frame structures mainly include beam-column and joint damage, wall cracking and non-structural component damage. The masonry-timber structure and brick-concrete structure were seriously damaged and collapsed accounted for a higher proportion of the overall earthquake damage of these two types of buildings, the number of severely damaged masonry-timber and brick-concrete structure was about 6 times for the frame structure, while no collapse was observed for frame structures, and the largely unbroken frame structure is relatively high. In general, the RC frame structures possess the strongest seismic capacity among these three types of structures, while masonry-timber structure present the weakest. According to the earthquake-damage characteristics of different structural forms, the earthquake-prevention capability of repairable earthquake-damaged houses and existing farm houses should be improved through seismic reinforcement, and some measures should be done to improve the earthquake prevention ability of rural buildings, and then the earthquake casualties and losses can be reduced.

Key words： Luding earthquake seismic damage investigation rural buildings masonry-timber structure brick-concrete structure RC frame structure
